Answer:
The height of the building is 18.8 feet to the nearest tenth
Step-by-step explanation:
Whenever an elevation problem is given the first step is to try to visualize a triangular path between the objects that are given in the problem.
In this case, we can form a triangular path between the man, the top of the building, and the ground.
The height of the building we are looking for will be the opposite side of the triangle because it is directly facing the angle: 38 degrees.
The distance 24 feet will be the adjacent side of the triangle because it is adjacent to that angle
We can use the Tan trigonometric relationship to find a relationship between the length of the sides of the triangle and the available angles.
approximately 18.8 ft
You have the equation
. To solve for the variable c, you need to get c on one side by itself to equal something. So the final answer should be
c = (some number).
The first step is to multiply both sides by 13. This will cancel the 13 in the denominator of the left side because 13/13 = 1.
Almost there... now we have to move the -2 to the other side. We can do this by adding 2 to both sides of the equation.
I decided to simply both equations:
75/4 *3 225/12
19/6 *2 38/12
First is to find a common factor which is 12, multiply both sides.
divide 38/225 and you should get 5.92.
